Christopher Kellie Design Inc. Thanks for your comment! For this we used a piece of the Mahogany decking material as a handrail and cables by American Cable and Rigging out of Asheville, NC. You could do something similar for a handrail with your existing Ipe. We've also worked with CableRail by Fenny, they have a great website that lets you order online or find a dealer in your area. Hope this helps, good luck!
Christopher Kellie Design Inc. These are real black locust posts from a company in Spruce Pine, North Carolina who revived the style of bark shingle siding and natural accents like posts and railings. You can get more information about their products at www.barkhouse.com
"In designing a home, we feel it’s extremely important not to design and build independently from the natural surroundings, and we incorporate the area’s native materials," says Simmons. The region and the site strongly influenced the home's shape, orientation and details. The home gives a nod to local and historical architectural traditions, takes full advantage of the views and is composed of elements like the bark shingles and locust posts.
